Kris Humphries Pockets $370G from Selling Engagement Ring

Kim Kardashian’s ex-husband Kris Humphries reportedly made a $370,000 profit from the sale of her engagement ring, and its designer Lorraine Schwartz is reportedly pissed.

The Boston Celtics star auctioned off Kim’s 20-carat diamond ring for $620,000 at Christie’s auction house in New York City on Tuesday, and jewelry designer Schwartz is reportedly furious because the bling – which features a 16.21-carat center diamond between two 1.8-carat diamonds – is actually worth $2 million.

A source told gossip website RadarOnline.com that Lorraine was hoping Hump would return the ring to her for a refund as she gave him a ”huge discount” and sold it to him for $250,000 in 2011 because Kim is her friend.

The insider said: ”He could have returned [the] ring, very low-key and would have had his money returned. Lorraine Schwartz took a huge loss on it, and would have appreciated first offer of refusal before it was put up for auction.”
